One Way Clutch Sprag Clutch RSCI20-130

One Way Clutch Sprag Clutch RSCI20-130

Feature

Type RSCI is a centrifugal lift off sprag type freewheel with the inner race rotating. Only the inner race is designed for freewheeling. It is a non self- supported type.

Bearings must be provided to ensure concentricity of the inner and outer races and support axial and radial loads, as shown overleaf. Concentricity and run-out limits must be observed. The RSCI type accepts all types of lubricant currently used in power transmission equipment. It is possible to mount these freewheels directly in gear-boxes without separate lubrication. An oil mist is generally sufficient. Grease lubrication may be acceptable if the unit works mostly in overrunning condition, as on E-motors.

When used as a backstop, it must be checked that the overrunning speed will not go below the minimum speed given in the caracteristics table. Please refer to page 78 (RSCI 180&ndash;300) for further information.

NOTES

1) T max = 2 &times; T KN

2) This maximum allowable torque transmission speed n max must not be exceeded when transmitting torque

3) This minimum allowable overrunning speed ni imin should not be reduced under continuous operation.
